With last year's $16 billion loss, combined with another increase in the price of stamps to 46 cents for a first-class letter, now "USPS announces that it will stop delivering on Saturdays" (Andrew Shilling - February 14).

Why not consider untapped revenue sources available to reduce operating deficits and perhaps even turn a small profit?

The Postal Service could sell advertising space on the sides of mailboxes and inside and outside the post offices, along with the small jeeps, regular trucks and heavy-duty long-haul trucks. Sell off some of the valuable real estate and move to less expensive locations.

Why not join banks and fast-food restaurants that sublet space at Walmart and other big-box stores to open smaller post offices? Generate both revenue and customers by subletting excess capacity at underutilized post offices to other city or state agencies, along with private sector businesses. License corporations to sponsor stamps for a fee.

Have members of Congress, State Legislature, City Council and other elected officials pay the real, full costs for their annoying frequent bulk-rate mailings to constituents. They are nothing more than free re-election campaign brochures subsidized by taxpayers anyway.

Why not apply free-enterprise solutions to provide a more cost-effective product, reduce deficits and prevent more branches from closing?
